Pierburg carburettors
We offer the repair / refurbishment facility for your 2E2 Pierburg carburettors as fitted to the 1600 and 1800 CL, GL, Driver and some Ryder manual transmission versions of the MK2 Golf, Scirocco, Jetta and Caddy.
Additionally, the same applies to the various 2E3 units as fitted to the 1300 Golf and 1900 DG engined Transporters T25 (T3 ) and
##### AS A SPECIAL ##### AND A LIMITED NUMBER OF AN
Improved performance version of the 2E3 Pierburg carburettors for the Vauxhall Nova 1300 for use as a track car
The following text is generally directed towards the 2E2 but, whilst completely different in operation the principles within the repair operation are the same
The background
This facility for 2E2 carburettor units is offered in the knowledge that some otherwise excellent vehicles are being scrapped just for the want of a repair that few Garages can undertake. The Pierburg 2E2 is an extremely good carburettor fitted to the Volkswagen range of 1600 and 1800cc engines between the years 1984 and 1992. There are 28 different engine codes and transmission within these years, each having different characteristics and, therefore, different requirements from the carburettor. The Pierburg carburettors are individually matched to that of the engine and there are, therefore, 28 different versions of 2E2 Pierburg to suit the different engine code and transmission set –up
The following is a brief outline of what the carburettor should achieve:
The basic unit incorporates a sophisticated design using 5 separate items to accommodate the automatic choke facility, which together with the specific settings particular to each engine code, allows for smooth starting and running at all differing ambient and engine temperatures. For the 1600/1800 set-up, the correct cold starting operation on these carburettors is, firstly, a speed of 2000rpm. This will be for up to 10 seconds depending on the ambient temperature, and the speed should then drop instantly to 1500-1600rpm which will then progressively reduce to 750 or 900 rpm, depending on the model, as the water temperature increases. During these 3 phases there should be a smooth tick-over and no hesitation on acceleration. Fuel consumption, overall, for the 1600 should be 37mpg, whilst the 1800 should return 35 mpg.
The repair details
For standard repair/re-furbished carburettors, each unit is completely stripped down and rebuilt with each part tested to meet the original specification and refurbished or replaced throughout. During the rebuild, the carburettors are subjected to over 60 tests and adjustments, typically as set out within the list below, such that all functions work correctly.
Each unit is run comprehensively on quality test engines and as such set-up to operate as they should throughout the cold starting, warming up and hot running condition. The carburettor is finally road tested from cold as a confirmation of the units behaviour in a real environment .
NB and a very important addition: The total rectification of a carburettor such that it performs in exactly the manner that it should can be a difficult and very time consuming operation.It is not something to undertake in a casual manner. I take the repair of your carburettor seriously and choose to take only one line with regard to the rectification of the unit. Therefore, THE CARBURETTOR WILL NOT BE FORWARDED UNTIL IT PERFORMS ABSOLUTELY CORRECTLY UNDER TEST. The carburettor needs to perform 100% before despatch. and this requirement does mean that scheduled dates for return of a unit can be delayed. You need to be aware of this fact.
THE REPAIR OPTION for the 2E3 is from £335 whilst the 2E2 is from £475 both + P&P via Courier 24hr @ £25.00
IMPORTANT :- It is necessary that the essential following information is made available prior to purchase of this offer.
The registration number of your vehicle
The full VW number of carburettor (usually on the top LHS) e.g. 027 129 015G 7 088
Existing carburettor running condition of revs and smoothness at :-
a) initial start from cold
b) warming up
c) hot idle
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
AS AN ADDITIONAL OPTION RE-CONDITIONED CARBURETTORS CAN BE SUPPLIED ON AN EXCHANGE BASIS.
On these units all metalwork is re-finished in order to provide an enhanced and additionally protected appearance, and as shown in the last photograph. For this option the cost is an additional £80 and with a surcharge amount that is returned in full on satisfactory receipt of the replaced carburettor.
